Flowchart symbol names and their uses


  • >Terminal points indicate the starting [sometimes known as a "trigger"] and ending points of a process.


>Step represents a single step within the process, and usually contains the name of the specific action.


>Page symbols refer to individual web pages, which may or may not contain multiple elements.


>File symbols represents those data elements that exist independently of navigational properties out of that page.


>A decision point indicates a sequence in the process at which the end user chooses an option and then branches to different parts of the flwcharts.


>Arrows and connecting lines diagram the logical progression through the course, subject to the choices made at decision within the process.

>The input or action symbol represents a user response that directs the course flow from the points onward.

>Conditional selector is similar to the conditional branch except that the user has the option to choose from a number of paths that will fulfill the requested conditions.

>Reference is used as a connecting point when the flowchart necessitates using more than one page, or refers to a complicated subroutine that would be impossible to contain on the main flowchart page.

>Annotations provide helpful comments or explanations.

>Flow references and flow areas are symbols for reusable sequences, such as logging in with a specific user id and password to enter the course or to initiate an on-line quiz. The flow reference symbol acts as a placeholder for the flow area sequence in the chart in every situation in which it is repeated. Flow area is used as a flow area, it documents sections that share similar components or repeated steps within that flow, and requires the use of the following two symbols: entry and exit points.

>Exit point concludes the subroutine, such as whenthe proper user id and password are verified, and documents where the user re-enters the master flowchart.

>Entry point documents the place within the master flowchart where the process deviates into a subroutine.
